Question
Ten bulbs are connected in a series circuit to a power supply line. Ten identical bulbs are connected in a parallel circuit to an identical power supply line.
- Which circuit would have the highest voltage across each bulb?
- In which circuit would the bulbs be brighter?
- In which circuit, if one bulb blows out, all others will stop glowing?
- Which circuit would have less current in it?

Solution
- The parallel circuit will have the highest voltage across each bulb.
- In a parallel circuit, each bulb has the highest voltage.
- The appliance can be controlled individually using an individual switch when a parallel circuit is used.
- The working of the appliances is not dependent on each other when they are connected in parallel.
